To @ZZ whom t may concern.: jecting from the top of thevalve, with which Be it known that I, ADOLPH WEBER,a citi` the key or wrench engages to operate the zen of the United States, residing at Detroit, valve. in the county of Wayne and State of Michigan, D is a cap or gland inserted in the upper 55 have invented new and useful Improvements end of the valve-case, cored out for the pasin Valves; and I hereby declare that the folsage of the valve-stem, and provided with lowing is a full, clear, and exact description the wings d d, which are perforated for the thereof, reference being had to the accominsertion of the screws EE.

The ports may be on opposite turned and the valve opened comes in consides of the valve-case, and the water-way tactwith the shoulder gand arrests the motion through the valve changed to suit the ports, of the key and the valve and leaves the valve thus forming a straight Water-way through open. By reversing the motion of the key roo 5o the valve. to close the valve the stud comes in contact O is asquare or rectilinear valve-stem profl with the shoulder g', and the further movement of the key and valve in that direction is arrested and the valve is left closed. This valve is opened to its full extent or closed by a quarter-turn of the key or wrench, While the ordinary radiator-valve, actuated by a screw on the valve-stem, requires several turns of the head to open the valve to its full extent. These ordinary valves require to be tightly packed around the valve-stem to prevent leakage, and in many cases the packing sticks to the valve-stem and the cap. In such cases the cap is often loosened and permits the escape of both water and steam, often to the great damage of the user. This leakage is totally avoided by my method of packing and by avoiding the use of a tightly-packed cap and valve-stem.

To avoid leakage and to insure a perfect Valve-seat for the valve, a recess L is cored out entirely around the interior of the valvecase, leaving an annular flange Z) around the induction port a. M and m are orifices through the valve-case and opening into the recess L. In the drawings these orifices are shown opposite to the port d; but they may be made at any convenient point. For the purpose of forming a true and perfect valve-seat Without the tedious and costly process of grinding the valve in its seat, the valve is inserted in the valve-case and so arranged that the entrance into the Water-way will open into the port a. A soft metal in a fluid state is poured into the orifice M until the recess L and the orifice M are completely filled. -Then the soft metal is cool, it forms the valveseat N, which is perfectly true, and the leakage is proportionately diminished.

3. The combination of the valve-case A, containing the valve B, with the valve B, the recess L, cored out of the valve-case to receive the soft-metal valve-seat, the annular flange around the port ce to prevent the outflow of the fluid soft metal, the orifice M, through which the fluid soft metal is poured to form the valve-seat, and the sott-metal valve-seat, all substantially as set forth.
